SPECIFICATION forming part of Letters Patent No. 613,086, dated October 25, 1898.

Application iled March 12, 1898. Serial No. 673,593. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, EZRA SMYTH, of Greencastle, in the county of Putnam and State of Indiana, have invented certain new and use ful Improvements in Switch-Derailers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form part of this speciiicatiou. y

This invention has relation to safetyswitches, and has for its object to prevent cars left on switches or sidings from running down upon the main track. This frequently happens, either from neglecting to put on the brakes, or from not checking the car-wheels, or in consequence of the car being blown by storm-winds, or the loosening of the car from its location by evil-minded persons, or from other causes, by all of which a passing train would be endangered. By my device the main track is always kept clear of obstruction at switches, thus removing the dread of `engineers at such points.

My invention consists of locating beyond the switch, on the siding, a structure upon which is located a derailing-switch so arranged as that when a car or train of cars are switched off on said siding they are prevented from running on the main track, as will be hereinafter more fully described.

In the drawings, Figure 1 is a perspective view showing my invention in position for derailing; Fig. 2, a plan view of the same, the derailing-switch being locked; Fig. 3, a crosssection taken on the line oc, Fig. 2 and Fig. 4 is a perspective view of one of the standards or supports for the derailing-switch.

In the drawings I only show one side of the railway-siding, as the other side would be simply a duplicate and therefore unnecessary.

The same letters will indicate like parts throughout all the iigures.

A is the rail, and B the cross-ties.

C are the standards or supports for the derailing-switch and switch-mate.

a are hinge-lugs to which the plate carrying the derailer is hinged, and Z) are the interlocking lugs forming the hinge and working between the lugs a a. The lugs a and b are cast integral-with their respective parts.

The supports C are firmly secured either by plates z' z or into the cross-ties B,orboth,which at this point are made wide, deep, and solid for the better foundation of the structure, as a shifting of these supports out of line would seriously interfere with the proper working of the device. These supports and hinges secure the derailing-switch in its locked position, and when not in use the de railingswitch is entirely out of the way, it being thrown back, as shown in dotted lines. (See Fig. 3.) It will be observed that the supports C have an upper flat surface c, projecting inwardly at' d under the switch-plate D for a better and more secure bearing.

Having described the foundations, supports, dsc., I will now describe the derailingswitcl1,which comprise the plate D,the switchmate E, the ascending rail or rib F, the downwardly-projecting stay-plate G, and the oblique plate H, having the cut-away f. All these pieces are preferably cast in a single piece, which at once makes the device much cheaper and safer than if made out of several pieces.

The locking-chain g is securedto the side of the stay-plate and is locked into a loop or staple h, fastened to the tie B, thus putting it beyond thepossibility of evil-minded persons tampering with or loosening the derailing-switch. Of course when the said switch is not in use and thrown back it may also be locked by the same chain to another staple, so that only those having authority can place and release the derailing-switch.

It will be observed that the derailing-switch when placed solidly on the track, the rail or rib F being on line on top of the railroadrail and the cut-away plate H lying obliquely on and across it, the chain g holding it down and-the stay-plate G holding it securely from lateral movement on one side, while the hinges 4secure it on the opposite side, and thus it is kept solidly in position against displacement by the movement of the cars.

The operation is simple and is as follows: The parts being preferably in place and the switch open, the chain is unlocked. Then the plate D is raised, Working in the hinges, and turned over on the railroad-rail, the rail or rib F and plate H resting 0n the said railroadrail and the stay-plate G reaching down over and snugly fitting it against the side of the railroad-rail, then locking the chain to the staple h, Where it remains until again unlocked. Thus any cars (one or more) should they move toward the main track (not shown) will be arrested by the derailing-switch, and if under great momentum they Will be derailed and thrown from the siding, thus preventing them from running out on the main track and leaving said main track free from obstruction as far as the switched-off cars are concerned.

It is obvious that slight changes and modiications may be made in the several parts Without departing from the spirit of my invention. I therefore desire not to be oonfined to the exact form shown, but consider myself entitled to all such changes as lie Within the scope of my invention.

I-Iaving described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. In a switch-derailer for sidings, the plate D, provided With switch-mate E, cut-away portion H, rail F, stay or safety plate G, and the vhinged lugs b, substantially as set forth.

2. The derailer comprising the plate D, switch-mate E, plate H, and inclined plate F, adapted to rest on the railroad-rail, the safety or stay plate G,in combination With the hinged supports or standards C, all operating together substantially as set forth.

3. The combination in a derailer of the supports or standards C having hinged lugs a, the flat supporting-face c, and projection d, to support plate D, the latter having hingelugs b, on one side, and safety or stay plate G, on its opposite side, the said hinges and supports preventing lateral movement of the derailer in one direction While the safety-plate G, prevents in the other, said hinges, supports and safety-plate G, being held in position by the plates D, and H, substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
